T azzw'hbmtmay 00mm; yBe it known-that LfLnANn E. Piton, a citizen of the United States, residingat,

Wyoming, in the county of Jones and State provements in Presses, ,of which the following is a specification.

j operation.

Another object is the provision of a press having anV accurate and effectivejfeeding mechanism whicnwill supplya'- maximumr amount .of power for Yfeeding with aeminimum of eorton thepart 0f the @Penton With tthe above land other objects in view, theA invention lfurther includes the Lfollowing novel features and details of construction, to be 'hereinafter more f fully described, ilA

lustrated in the raccompanying drawingsand' pointed -out in the-appended claims.

lIn the-drawingsI:-,-

f v Y i Figurel'is a-` front'elevation of va press embodying the present invention. y Figure 2is an edgeview of the same.;A

Figure 3 is a section'on the line v3-13 of F igure `1, Figure 4 is a of Figure 1.

Figure 5 is a vertical section on the line 5 5 of Figure 1. f

Figure 6 is a similar view on the line 6 6 of Figure 1. Y

Referring in detail to the drawings, wherein like characters of reference denote corresponding parts, the reference character 10 indicates the base of the press frame which is preferablyformed of channel iron similarviewl oli-the line 4 4' and froniwhich rises channeled side meme f bers 11, the latter being connected at their upper ends by means of a channel beam 12 to provide a substantially rectangular vertical frame. This frame issupported in an upright position by means of horizontally arranged bars 13 which are connected to the side members 11 by braces 14. Also connecting the side members 11 and spaced from the channel bar 12, is a channel beam 15, which is provided near yeach end with vertically disposed ybearings y The; re ceiveone ,end of gvertically disposed shafts 18, whose opposite lower ends aremounted in bearings 19 `secured tog the Ibase 10;-

The'shafts 18 arethreaded hroulgglioutditl greater portion of their lengths, and mounted f for movement longitudinally, Q` these shafts His a table 20wnich is preferably constructed of two 4channel iron bars 21l arranged .j side by sideand carrying at each end internally,

threaded sleeves `or nuts 22. ',Thesegslee'ves or nuts 22 are secured ytothe table as .indivir cated at, 23 l and f'extending fromthe outer sidesof the saidfsleeves or .nuts diametric,allyL opposite' lthetable-20 ,are rojections 2d,

which ,engage andfsldeffree yionfthe side members `11. The nuts orsleeves `22 are, secured to the table 20 andthe extensions 2&1,- as,indicated.at25, l I

The. rotation Aof ,the shafts .18 Will,thr0ugl1 move the table vertically, the directionof, movements being controlled :by lthe direction of rotation ofthe shafts, I In-order to rotate these shaftsthere is secured to ktheir upper ends a vgear-1 26,Wl1i011 .sengagd and driven from a worm 2 7, mounted upona shaft '28, one of these worms being provided foreach of the gears 2 6 sojthat the/Shafts 1 8fwill be simultaneously rotated.l The shaftf2 is mountedy in, suitable bearings carried b the side v,members l1 and extends ,beyfon one of said members,where it is provided with a hand .wheel29f4 The ythreads ,of the Shafts *'18 are preferably of a ,righthandpitch Mounted in a bearing 30 whichY is secured to the beams 12 and 15, is avertically disltheir engagement vwith the sleeves tor nuts 22,;

posed shaft 31, theupper portion of which is formed with a longitudinallydisposed keyl way 32,-which is engaged by a key 33 extend` ing from the upper en-d of the bearing 30.- The shaft31 is formed fora rportionof its length with a left hand thread 34 and mounted upon the threaded portion of the shaft is asleeve or nut 3 5., The upper end of this sleeve is swiveled in a bracket or bearing 36, which is secured to the under edge of the beam 15 as shown at 37 and located within this bracket or bearing 35 are antifriction devices 38.-

Secured to the sleeve or nut 35 is a hand l wheel 39, the latter having in turn secured thereto, a ring gear 40. This ring gear is engaged by apinion l1 secured to one end of a shaft 42, the said shaft being-mounted edge of the beam 15. In addition. the shaft 42 is provided Vat'its outer end with a gear 43', which is engaged by Va pinion 44, secured upon the inner end of a counter shaft 45. This last mentioned shaft is mounted in suitable bearings 46 which are carried by the frame of the machine and extends beyond one Vof the side members 11 and' has secured thereon a hand wheel 47. Also mountedupon the shaft 45 lis a ratchet wheel 48, the teeth of which are engaged by a` spring actuated dog 49 carried by a i hand lever 50. Y This lever is mounted for swinging movement upon the shaft 45 and its latch is controlled by a hand lever 51.

Key 33 prevents `shaft 31 from turning witlrnut 35, when the latter is turned around in the bracket 36, lthereby enabling the threads of the nut to exert a thrust vertically vof the shaft for sliding the same' lup or down thru guide-bearing 30'. The shaft 31 'may thus be vertically reciprocated through the medium of either vthe hand lever 50 or'the hand wheel47, the latter increasing the power applied to the shaft through the'medium of the gears 43 and 44, This power may be further increased changes in its form, proportions andv minor claims.

details of construction andthe right is here'- in reserved to make such changes as prop-vk erly fall within' the scope of the appended Having described the Vinvention what is claimed is 1. A device of the character described comprising a vertical frame presenting a work-table at its lower portion and a verticallyJ disposed internally threaded bearing at its upper end and overlying` the said tool-holder threadedly engaging the said f' bearing and-the threaded bore of the said jgear, a shaft journaled in bearings horizontally of the said frame, a pinion on one end of the shaft engaging-the said gear, and means at the other end of the said shaft for rotating the shaft'.

2. A device of the character described comprising a frame 'having an internally threaded vertically disposed bearing at its upperend, a work-table mounted on the frame below the said bearing, a gear swiveled in al bracket at the lower end of the bearing and presenting a threaded bore in line therewith, a tool-holder extending;r through the 'said bearing and the threaded bore of the said gear, and being threadedly engaged with each, forwardly and rearwardly arranged shafts journaled horizontally in bearings on the said frame and in spaced parallel relation to each other," a pinion on the forwardly arranged shaft engaging the said gear, means on the rearwardly arranged shaft for imparting ro-l tation thereto, and gearing between adjacent ends of the said shafts. v

*3. A device of the character described comprising' a vertical Vframe having a vertically disposed bearing at its upper end, a vertically adjustable work-table mounted on the frame below the said bearing, a gear swiveled in a bracket atV the lower end of the said bearing and presenting a threaded bore in line with the bearing, a tool-holder extending through the `said bearing and the said bore and threadedlyienga'ging the latter, and means for imparting rotation to the said gear including a shaft and a ratchet mechanism forturning the shaft.

In testimony whereof I aix my signature.
